S3, E19: Nick and Reese investigate a trail of murders only to discover that the lead suspect is a Hitler-type racist from Reese's past. When the killer devises a plan to get Reese removed from the case, the Captain's rage intensifies. Concerned that Reese may be on a personal vendetta, Nick soon learns that the Captain is one step ahead of the killer (and him) in cleverly obtaining incriminating evidence.
